The assembled genome is composed of a 2,861,352-bp circular chromosome, a 2,058,040-bp linear chromosome, a 519,735-bp AT plasmid, and the 223,394-bp Ti virulence plasmid. The wild nondisarmed strain produces small gall-like structures in citrus.
The complete genome sequence of the gammaproteobacterial isolate Serratia quinivorans 124R consists of 5 Mb over 2 scaffolds and a G+C content of 52.85%. Genes relating to aromatic metabolism reflect its isolation on organosolv lignin as a sole carbon source under anoxic conditions as well as the potential for lignin biorefinery applications.
Haematobacter massiliensis OT1 was isolated from human skin. This strain can catabolize 4-hydroxybenzoate. Here, we present the first complete whole-genome sequence of this species, which has one chromosome (2,467 kbp) and nine plasmids (total of 1,765 kbp). The analysis of the H. massiliensis OT1 genome indicated a potential for autotrophic growth.Copyright © 2019 Lim et al.
We report the complete genome sequence of a colistin-resistant strain of uropathogenic Escherichia coli, isolated in January 2013 at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia. The isolate (named SA186) was sequence type 131 (ST131) and belonged to serotype O25b-H4 and clade B (fimH22).Copyright © 2019 Alghoribi et al.
USA300 is a predominant community-associated methicillin-resistant Staphylococcus aureus strain causing significant morbidity and mortality in North America. We present the full annotated genome sequences of two methicillin-resistant Staphylococcus aureus isolates related to the USA300 pulsotype with the goal of studying the evolutionary relationships of this highly successful strain type.Copyright © 2019 McClure and Zhang.
Myxobacteria are a source of unique metabolites, including corallopyronin A (CorA), a promising antibiotic agent in preclinical development for the treatment of filariasis. To investigate the production of CorA on the genetic level, we present the complete 9.6-Mb genome sequence of the CorA producer Corallococcus coralloides B035. Copyright © 2019 Bouhired et al.
Predominant community-associated methicillin-resistant Staphylococcus aureus strain USA300 is believed to have originated from an ancestral methicillin-susceptible strain, although the details of that evolution remain unknown. To help understand the emergence of this highly successful strain, we sequenced the genomes of two methicillin-susceptible Staphylococcus aureus clinical strains that are very closely related to USA300.

Achromobacter spanius UQ283 is a soilborne bacterium found to exhibit plant growth-promoting and disease-suppressing attributes in several plant species. Accordingly, we used long-read sequencing to determine its complete genome sequence. The assembled genome will aid in understanding the multifaceted interactions between plant growth-promoting rhizobacteria, pathogens, and plants. Copyright © 2019 Wass et al.
Here, we present the complete genome sequence of a Shewanella isolate, TH2012, from a shrimp pond in which shrimp exhibited early mortality syndrome (EMS)/acute hepatopancreatic necrosis disease (AHPND). The complete genome of TH2012 has a prophage-like element and a number of potential virulence factors, making TH2012 a possible contributing factor to EMS outbreaks.

Klebsiella pneumoniae 2N3 is a strain of gram-negative bacteria that can degrade chlorimuron-ethyl and grow with chlorimuron-ethyl as the sole nitrogen source. The complete genome of Klebsiella pneumoniae 2N3 was sequenced using third generation high-throughput DNA sequencing technology. The genomic size of strain 2N3 was 5.32 Mb with a GC content of 57.33% and a total of 5156 coding genes and 112 non-coding RNAs predicted. Two hydrolases expressed by open reading frames (ORFs) 0934 and 0492 were predicted and experimentally confirmed by gene knockout to be involved in the degradation of chlorimuron-ethyl. Strains of ?ORF 0934, ?ORF 0492, and wild type (WT) reached their highest growth rates after 8-10 hours in incubation. The degradation rates of chlorimuron-ethyl by both ?ORF 0934 and ?ORF 0492 decreased in comparison to the WT during the first 8 hours in culture by 25.60% and 24.74%, respectively, while strains ?ORF 0934, ?ORF 0492, and the WT reached the highest degradation rates of chlorimuron-ethyl in 36 hours of 74.56%, 90.53%, and 95.06%, respectively. This study provides scientific evidence to support the application of Klebsiella pneumoniae 2N3 in bioremediation to control environmental pollution.
Isolated from Aran-Bidgol Lake in Iran, and reported here, Halorubrum ezzemoulense strain Fb21 represents the first complete genome from this archaeal species. Local recombination in this genome is in stark contrast to equidistant recombination events in bacteria. The genome’s GC bias, however, points to a genome architecture and origin that resemble those of a bacterium. Its availability, genome signatures, and frequent intragenomic recombination mean that Fb21 presents an attractive model organism for this species. Copyright © 2019 Feng et al.
Deinococcus wulumuqiensis 479 (formerly known as Deinococcus radiodurans 479) is the original source strain for the restriction enzyme DrdI. Its complete sequence and full methylome were determined using Pacific Biosciences single-molecule real-time (SMRT) sequencing. Copyright © 2019 Fomenkov et al.
The vaginal bacterial strain AB70, belonging to the species Lactobacillus crispatus, was isolated from a vaginal swab from a healthy pregnant Korean woman. Here, we report the 2.37-Mb complete genome sequence of this strain. Copyright © 2019 Chang et al.
The phytopathogen Spiroplasma phoeniceum was isolated from diseased plants of Madagascar periwinkle [Catharanthus roseus (L.) G. Don]. Here, we report the nucleotide sequence of the 1,791,576-bp circular chromosome and three plasmids of strain P40T This information serves as a resource for comparative analyses of spiroplasmal adaptations to diverse ecological niches.
Enteropathogenic Escherichia coli (EPEC) is a leading cause of moderate to severe diarrhea among young children in developing countries, and EPEC isolates can be subdivided into two groups. Typical EPEC (tEPEC) bacteria are characterized by the presence of both the locus of enterocyte effacement (LEE) and the plasmid-encoded bundle-forming pilus (BFP), which are involved in adherence and translocation of type III effectors into the host cells. Atypical EPEC (aEPEC) bacteria also contain the LEE but lack the BFP. In the current report, we describe the complete genome of outbreak-associated aEPEC isolate E110019, which carries four plasmids. Comparative genomic analysis demonstrated that the type III secreted effector EspT gene, an autotransporter gene, a hemolysin gene, and putative fimbrial genes are all carried on plasmids. Further investigation of 65 espT-containing E. coli genomes demonstrated that different espT alleles are associated with multiple plasmids that differ in their overall gene content from the E110019 espT-containing plasmid. EspT has been previously described with respect to its role in the ability of E110019 to invade host cells. While other type III secreted effectors of E. coli have been identified on insertion elements and prophages of the chromosome, we demonstrated in the current study that the espT gene is located on multiple unique plasmids. These findings highlight a role of plasmids in dissemination of a unique E. coli type III secreted effector that is involved in host invasion and severe diarrheal illness.Copyright © 2019 American Society for Microbiology.
